On several occasions, we've deleted an Agent from the Control-M Configuration Manager, only to have it re-appear later. In recent cases;1) 12pm Wed: checked AJF for jobs defined to host; only job in AJF had completed hours earlier2) 12pm Wed: checked host groups for host and removed it. 3) 12pm Wed: no jobs found in planning that execute on the host.

4) 12pm Wed: successfully deleted Agent/host from CCM

5) New Day scan ran at 2pm Wed; no jobs scanned to in AJF for Host

At some point, the agent returned to the CCM, no jobs in AJF, host is not found in any Host groups.

We are on v8.0.00.500 of the EM and will be upgrading to v9 in the coming months. I modified the "CmsHostSpecRetrieverInterval" parameter to "0" as suggested in the KA and will confirm Monday that they don't reappear. Thank you!

If your Control-M Server is in Windows box please run "ipconfig/flushdns" in command prompt and then recycle Control-M Server process and for unix box please do restart nsdl and recycle Control-M Server processes.

Option-2

Instead of directly deleting the failed agent, please do disable the agent first from CCM and then delete.
